Sightron SIII 10-50×60 FT Field Target Riflescope

The Sightron SIII 10-50×60 FT is a high-magnification riflescope developed around Field Target competition. It combines a broad 10-50x magnification range with a large 60 mm objective lens and close-range parallax adjustment designed specifically for the distances commonly encountered in Field Target use.

Sightron gives the FT version a side-focus system that adjusts from 10 to 300 yards. As a result, the scope differs from the SIII Long Range 10-50×60, whose parallax adjustment runs from approximately 13 yards to infinity.

At the same time, the 30 mm main tube, large 60 mm objective and long optical body give the scope the traditional proportions associated with high-magnification target optics.

You can find the current model information through the official Sightron SIII Field Target 10-50×60 page.

Sightron SIII 10-50×60 FT Optical Design

The Sightron SIII 10-50×60 FT provides variable magnification from 10x to 50x.

At the lower end, the scope provides a wider viewing area. Meanwhile, increasing the magnification toward 50x enlarges finer visual details while narrowing the field of view.

Sightron specifies a field of view of approximately 9.6 to 2.2 feet at 100 yards, depending on the magnification setting.

Therefore, the optical system clearly reflects the scope’s competition-focused character.

Rather than using moderate magnification typical of a general-purpose sporting optic, Sightron gives the FT model a much higher upper range for applications where fine visual detail matters.

10-50x Magnification Range

The 10-50x zoom range forms one of the most recognizable features of the SIII FT.

At 10x, the scope provides its widest field of view. At 50x, the image appears considerably larger and the field becomes much narrower.

As a result, the optic covers a 5x zoom range without changing scopes.

The 50x maximum magnification also explains the large overall dimensions and target-oriented controls.

In addition, Sightron uses the same basic 10-50x optical range across several competition and long-range models, although those versions can differ in parallax range, reticle and turret configuration.

60 mm Objective Lens

The SIII FT uses a large 60 mm objective lens.

This gives the front of the riflescope its broad profile and distinguishes it immediately from smaller 40 mm, 44 mm or 50 mm target optics.

The 60 mm objective works together with the high-magnification optical system. Therefore, it remains one of the most important specifications to include in the product title.

For WooCommerce, the clean specification is:

Objective Lens Diameter: 60 mm

There is no need to repeat “60 mm objective” in every section simply for SEO.

Field Target-Specific Parallax Range

The parallax system provides one of the main differences between the SIII FT and other Sightron 10-50×60 scopes.

Sightron specifies the FT model at:

10 yards to 300 yards

using a side-focus control.

Because of this, the FT version can focus considerably closer than many general long-range scopes.

The standard SIII Long Range 10-50×60, by comparison, focuses from approximately 13 yards to infinity.

Therefore, do not copy the Long Range parallax specification onto an FT product page.
